| 摘 要： | 为了了解回采工作面刮板输送机圆环链在卡链状态下力学性能,文中利用ANSYS/LS-DYNA软件,对含有V型缺口圆环链进行数值模拟冲击实验分析,特别是就低温和应变率等因素对圆环链冲击性能的影响进行了比较详细的研究和讨论.研究结果表明温度降低会导致矿用受冲击圆环链破断时吸收能量减小和缩短初始破断时间,另外,应变率(加载速率)也会使破断应力增大和缩短初始破断时间.

| Abstract: | To understand the mechanical property of chain in scraper conveyor under the suddenly struck condition,the impact experimental process of round-chain with V-notch is numerically simulated and analyzed by using ANSYS/LS-DYNA code,and the effects of the low temperature and the strain rate on the impact property of chain are discussed.The results of the investigation indicate that the adopted energy will decrease and initial breaking time will shorten as the test temperature drop,furthermore,the strain rate(or... |
